France’s National Agency for Medicines and Health Products Safety (ANSM) broadened its Autorisation d’Accès Compassionnel (AAC) protocol on January 12, 2026 to include the investigational combination of botensilimab (BOT) and balstilimab (BAL). The new framework now allows reimbursed, hospital‑based compassionate access for patients with certain ovarian cancers and soft‑tissue sarcomas, in addition to the previously authorized microsatellite‑stable metastatic colorectal cancer (mCRC) cohort.
The expansion is a strategic win for Agenus, as it extends early‑access availability beyond colorectal cancer and enhances the company’s ability to generate clinical evidence and potential revenue streams in a key European market. By enabling reimbursed access, the program provides a structured mechanism for collecting safety and efficacy data in a real‑world setting, which can support future regulatory submissions and commercial launch plans.
Agenus’s CEO, Garo Armen, emphasized the unmet medical need addressed by the program: “This is a breakthrough for patients and their physicians. MSS colorectal cancer resists current immunotherapies, and treatment options after standard regimens are very limited.” The same sentiment applies to ovarian cancer and soft‑tissue sarcomas, where BOT+BAL has shown durable responses in early studies.
Financially, Agenus has been focusing on cost‑cutting and improving its cash position. The company’s recent quarterly results highlighted a net loss driven by ongoing clinical development expenses, but the expansion of the AAC program is expected to mitigate cash burn by generating reimbursed revenue and providing a platform for future commercial opportunities. The company’s management has indicated that the expanded access will help maintain momentum in its core BOT/BAL program while supporting broader pipeline development.
The market reaction to similar regulatory milestones has historically been positive, as seen when France granted reimbursed access for BOT/BAL in MSS mCRC in November 2025, which contributed to a notable stock rally. Investors view such approvals as a signal of regulatory confidence and a step toward broader commercialization.
Overall, the AAC expansion positions Agenus to accelerate data collection, strengthen its competitive positioning in immuno‑oncology, and potentially unlock new revenue streams in Europe, reinforcing the company’s long‑term growth strategy.
